Description
Measures for quality assurance in welding the outer shell of WTSt 52-3 steel of the SNR 300 nuclear power plant in Kalkar/Niederrhein are presented, the causes for the microcracks found in welded joints (light microscope, microprobe) are also investigated. These occured above all when using stick electrodes with alloyed cladding, less with electrodes alloyed in the core and hardly in CO2 weldings. These can be practically avoided by limiting the copper content in the welding material to about 0.40%. (orig.)
Abstract (German)
Dargestellt werden Massnahmen zur Guetesicherung beim Schweissen der Dichthaut aus WTSt 52-3 des Kernkraftwerkes SNR 300 in Kalkar/Niederrhein, daneben die Ursachen von in Schweissverbindungen gefundenen Mikrorissen (Lichtmikroskop, Mikrosonde) untersucht. Sie traten vor allem bei Verwendung huellenlegierter Stabelektroden, weniger bei kernstablegierten und nur selten in CO2-Schweissungen auf. Praktisch vermeiden lassen sie sich durch Begrenzen des Kupfergehaltes im Schweissgut auf etwa 0,40%. (orig.)Additional details
